Nowadays, very few people waste their coins on gambling. In 2011 and 2012, there were so few options available for users to spend their coins. Most of them tried their luck on sites such as Satoshi-Dice, since Bitcoin was not being accepted anywhere else. But the situation has changed now. Currently there are a lot of options to spend your coins.
If that will change soon than there will be a lot of people that is getting a lot of profit and that would be nice.
I dont really mind if i spend my bitcoin for this early stage as long as im using it for good, but my other ways where i spend my bitcoins is at gambling,tradings and investing and i think majority of us do the same way as i do, because thats the only use for bitcoin for now.
